Emergency Escape and Rescue
I inspected this 2003 yr built home today with a basement window sill height of 53 1/4", I know its too high, should be 44". I wonder what happened during the construction of the house, nice middle class neighborhood. I don't have a IRC book for 2000, I was wondering what the code said (44" correct ?)

Re: Emergency Escape and Rescue
Maybe there's another egress window? Or it was permitted for another purpose.

Re: Emergency Escape and Rescue
From the 2000 IRC:
R310.1 Emergency escape and rescue required. Basements with habitable space and every sleeping room shall have at least one openable emergency escape and rescue window or exterior door opening for emergency escape and rescue. Where openings are provided as a means of escape and rescue they shall have a sill height of not more that 44 inches (4118 mm) above the floor. (blah, blah-blah, blah-blah - too much to type and not applicable to the question) Escape and rescue openings with a finished sill height below the adjacent ground elevation shall be provided with a window well in accordance with Section R310.2.
The question now is - was the 2000 IRC applicable in TN at that time? Even if not, the IRC had just come in as the consensus 'national standard' for the construction of one- and two-family dwellings (didn't cover townhouses in 2000 IRC - townhouses would have been under the IBC in 2000).

Re: Emergency Escape and Rescue
By the way, that "sill height" is 54".
The "sill height" being referred to is the bottom of the opening when the window is open.
The window opening size is measured with the window open: height (bottom of opening to top of opening), width one side of opening to the other side of the opening), overall square feet (height inches times width inches divided by 144 gives square feet or opening), from the floor inside (floor to bottom of opening - more than 44" not allowed), and from the ground outside (ground to bottom of opening - more than 44 inches and the minimum opening size goes from 5.0 sf to 5.7 sf to allow for ladder to intrude into opening).

Re: Emergency Escape and Rescue
The builder probably called it a bonus room thus not having to meet the bedroom EE & R requirements.

Re: Emergency Escape and Rescue
Didn't matter - in basements, it is habitable space shall have at least one EERO , "and" every sleeping room in the house.
Basements with habitable space only - at least one EERO.
Basements with habitable space and a bedroom - at least one EERO in bedroom "and" at least one EERO for the habitable space.
Even more requirements today, that was in 2000.

... just pointing out for the future where one measures to, and why.

Re: Emergency Escape and Rescue
It possibly can matter, for trying to understand where it fell apart, if the basement was simply a wide open room upon approval, and there was an EERO in the basement.
Someone could have added a bedroom or "finished" the basement off book, changing the location of the EERO. Wouldn't be the first time.
That's just to illustrate a potential scenario.

Re: Emergency Escape and Rescue
The above is what I quoted as what I was replying to, and, to that, as I previously said:
Which, I thought, pretty much covered any scenario - 'habitable space only', 'bedroom', 'bedroom and habitable space'
Which does not address what I was replying to:
That said ... it likely "fell apart" when it was constructed ... but we don't know the answer to that possibility.

Re: Emergency Escape and Rescue
The 10" difference would require 2 risers, and to be able to use the top tread as a 'floor' area to measure from, the top 'tread' would need to not only be as wide as the window, the top 'tread' would need to be a "landing" - minimum 36" from the wall.
If the bedroom is large enough to give up an area of about 4 feet out from the wall by the width of the window, I don't see why that wouldn't work. Provided that the window meets the other EERO requirements.
Permanently installed, of course.

Re: Emergency Escape and Rescue
There is a nearby condo/townhouse development (I think from the late 1980s or early 1990s) where the windows were too high to meet EERO requirements. So, the builder installed metal, fold-down steps that are attached to the wall below the operable sash. Apparently, the AHJ was ok with it.

Re: Emergency Escape and Rescue
The AHJ has no liability for it either.
The home inspector, by recommending such a fix, puts themselves first in line for any and all liability for anything related to such a fix.
Which includes any injuries from bumping into those steps, or high school prom gowns getting caught and torn on such ... whatever 'injury' which might happen to anyone.
Far better to advise the buyer of the condition and then not suggest any fix less than a full and proper fix.

Re: Emergency Escape and Rescue
I understand, but sometimes there just is no fix and I struggle with these. I have seen a couple of instances where it is the result of poor design and I cannot imagine any correction short of some significant demolition, which frankly won't be done until the building comes down.

Re: Emergency Escape and Rescue
I absolutely agree.
But ... does that mean that the home inspector should take it upon themselves to offer a less than required fix?
No.
Explain the issue. Explain the fix. When the client says 'the seller will never do that', you say 'you are probably correct' ... then add 'but that is what needs to be done' ... and, if you feel like you need a different out, offer 'you can check with the local building department and see what they say'.
Put it back on the AHJ, the ones who (supposedly) approved the work (unless it was unpermitted work). Let the AHJ tell them what they should do, after all, it was the AHJ which approved the work as it now exists.
If the client comes back and says that the AHJ says 'we don't see a problem with it', then tell your client to send them an email "to confirm the phone conversation", and then save the return email which says that ... and if they don't get a written response saying that same thing ... then it wasn't anything your client could hang their hat on anyway ... spoken words are nothing more than mutterings into the wind ... saying nothing and meaning nothing.
